"JAMES c. GEORGE AND GABRIEL L. enonen, or BRISTOL, VIRGINIA.

FURNAOE-GRATE.

Application filed Uctober 26, 1915.

To all whom it may concern:

Be it known that we, JAMns C. GEORGE and GABRIEL L. GEORGE, citizens of the United States, residing at Bristol, in the county of Washington and State of Virginia, have invented certain new and useful Improvements in Furnace-Grates, of which the following is a specification. V

This invention relates to a furnace grate and more particularly to that class of grates most appropriately termed sectional construction.

It is well known in the trade that furnace,

grates burn out and are subject to renewal frequently and efforts have repeatedly been made to produce a properly designed sectional grate having the parts so disposed, arranged and constructed that when one part burned out, or was otherwise damaged, new part could be substituted therefor without difficulty. Furthermore, it is also a fact well known that, generally, the ends or hangers of the grate burn out first and therefore necessitate the renewalof the entire grate. I

Therefore, one object of the present 1nvention resides in a construction of grate bar embodying a main bar carrying grate sections and hangers removable or detachable from said main bar and grate sections but supporting the same in a furnace. Thus, should the hangers burn out it is possible to replace the same with new hangers at com paratively low cost when taking into consideration the expense of an entire new grate or even the main bar.

A further object resides in the novel form of main bar and hangers which are so designed as to be comparatively simple and cheap to manufacture.

And yet another object resides in the spe cific arrangement of main bar, hangers and lVith the above and other objects in view one specific manner of practising this invention is shown in the accompanying drawing, in which:

Figure 1 is a view in perspective showing a grate bar constructed according to the present invention, and with parts bro-ken away to Show the details of the hanger construction.

Fig. 2 is a central sectional view taken Specification of Letters Patent.

Serial No. 57,935.

Fig. 4 is a perspective view of a modified form of hanger for use with a rocking grate construction. 1

. In] detail:

-'The grate bar, as shown, comprises the main bar 1 which is substantially rectangular in form and is provided on the sides 2 with lugs 3 which serve to engage similar lugson the next adjacent grate bar and thus properly space the two apart. The ends 4: of the main frame 1 are provided with ears 5 for purposesto be hereinafter described. The sides 2, of the main bar 1, may at suitably spaced distances be reinforced by connecting webs 6.

The main bar 1 carries the grate sections 7 which are identical in construction and therefore interchangeable. Each of the sections 7 is substantially rectangular and includes a frame 8 provided on the sides with lugs 9 and on the ends with ears 10, the lugs 9 serve the same function as the lugs 3 on the main bar 1, while the ears l0 serve to properly space the grate sections 7 apart. Each grate section 7 is provided, on the bottom, with the depending flanges 11 which are cut in at 12 on each side to form shoulders for engagement with the sides 2 of the main bar 1, whereas the flanges themselves depend within the main bar 1 and form a supporting medium for the sections 7 relative to the main bar which prevents displacement of the latter.

The hangers 12 (see Fig. 3) each comprise the top ledge 13 which may be suitably shaped on the outside to engage the furnace wall and on its inner edge is provided with lugs 14 to engage the cars 10 of the next adjacent grate section 7. Depending from the ledge 13 is the hanger wall 15 which, at the bottom, extends inwardly, as shown at 16, and thence upwardly as at 17, thereby forming a hook-shaped seat to receive the ends 4: of the main bar 1.

In assembling the gratein a furnace, the hangers 12 are placed in position on the walls of the fire-box-of the furnace and the main frame 1 then seated in the hangers as shown in Figs. 1 and 2; the grate sections 7 Fig. 3 is a perspective view of one hanger and Patented Mar. 27, 1917.

are then placed in position on the main bar and the whole forms a rigid sectional grate structure parts of which may be renewed, at comparatively low cost, as use requires.

The same construction may be used in a rocking grate except that the hangers must be modified accordingly. Therefore, in Fig. l the hanger 12 which is adapted for use with a rocking grate construction, comprises the ledge 13 carrying the dependent wall 15 which, at the lower end, is. eX- tended inwardly as at 16 and thence upwardly as at 17 to provide a seat for the main bar. Also the wall 15 is provided with the boss 18 carrying the pintle 19 which, when the grate is assembled in the furnace, is journaled in the wall of the firebox.

\Vhile, in the drawing and foregoing description, we have set forth a specific form of practising our invention, it is to be distinctly understood that, in practice, We may Copies of this patent may be obtained for five cents each, by addressing the resort to such modifications as fall within the scope of the invention as defined in the appended claims.

l/Ve claim: I

1. A grate embodying a hanger having a lower hook-shaped seat, and a frame having one end abutting said hanger and engaging said seat.

2. A grate embodyinga pair of hangers having lower hook-shaped seats, an elongated open frame having its ends abutting said hangers and engaged in said seats, and removable grate sections seated in said frame.

In testimony whereof we have hereunto set our hands in the presence of two subscribing witnesses.
